overexpressed in many human cancers. Therefore, the PI3Kα was considered as a promising target in therapeutic treatment of cancer. In this study, two series of compounds containing 2H-benzo[b][1,4]oxazin-3(4H)-one and 2H-benzo[b][1,4]oxazine scaffold were synthesized and evaluated antiproliferative activities against three cancer cell lines, including HCT-116, MDA-MB-231 and SNU638. Compound 7f with the most potent
PI3K信号通路的异常激活导致各种癌症的发生。PI3Kα在许多人类癌症中经常发生突变并过表达。因此,PI3Kα被认为是治疗癌症的有希望的靶标。在这项研究中,合成了包含2 H-苯并[ b ] [1,4]恶嗪-3(4 H)-one和2 H-苯并[ b ] [1,4]恶嗪骨架的两个系列化合物,并评估了其抗增殖能力对三种癌细胞系(包括HCT-116,MDA-MB-231和SNU638)具有抗肿瘤活性。选择具有最强抗增殖活性的化合物7f用于对正常细胞和PI3K激酶的进一步评估。研究表明图7f可以剂量依赖性方式降低磷酸化Akt(T308)。在7f与PI3K酶的对接中发现了四个关键的氢键相互作用。所有结果表明7f是有效的PI3Kα抑制剂。
